Mol-1 of ozone are compared to those from the control run, indicating that from the heading to mature stage contents of chlorophylls a and b as well as the total increase first and then drop, but the carotenoid content and the value of value of chl a/b keep steadily rising and declinling, respectively, there is no significant decrease in the net photosynthetic rate and stomatic conductance during the early stage of heading but their drops increase gradually with prolonged smoking time.

mol-1的O3处理下，与对照相比，从抽穗期到成熟期冬小麦叶绿素a、叶绿素b和总叶绿素含量均呈先上升后降低的变化趋势，而类胡萝卜素的含量和Chla/b的比值则分别持续升高和下降，净光合速率和气孔导度在抽穗初期无明显下降，但是随着熏蒸时间的增加下降幅逐步变大。

The results have showed that though there are diversity on the content of cholrophyll in the different stages of growth and development at the same breed species, the mean content of chlorophyll displays the law "low—high—low"from the trilobe to the maturing phr...

L under high temperature sterilization. The condition of complexion of Zn2+ with chlorophyll to stabilize the chlorophyll to prevent the browning of chlorophyll in green Typha latifolia.L is studied.

并对利用锌离子与叶绿素高温复合反应稳定叶绿素以防止绿化蒲菜中叶绿素的褐变的工艺条件作了初步探讨。

Wheatgrass contains an abundance of chlorophyll. The structure of chlorophyll is similar to that of hemoglobin, which makes it possible for our body to convert chlorophyll into hemoglobin.

小麦草含有丰富的叶绿素，叶绿素与血红素的结构非常相似，所以人体可以把叶绿素转化成血红素。

At last, the combination of chlorophyll meter and the remote sensing, the use of chlorophyll fluorescence technique in the nutrition diagnosis of plant nitrogen, and the assessment of the forest ecosystem health and the evaluation of ecosystem services by the nutrition diagnosis of plant nitrogen, were discussed.

根据植物氮素营养诊断的发展脉络，总结了化学诊断和无损测试技术的主要内容，重点阐述了植株硝酸盐快速诊断、叶绿素仪和遥感技术在作物氮素营养诊断及氮肥推荐中的应用原理、优缺点以及发展现状，提出可将叶绿素仪和遥感技术结合使用、利用叶绿素荧光技术诊断植物氮素营养以及将植物氮素营养诊断技术应用于森林生态系统健康和生态系统服务功能的评估。

The results showed that under increasing field temperature in the period from male tetrad to maturing stage, the grain yield of ND108 and YD13 decreased by 46.6% and 45.1%, leaf area index decreased by 15.4% and 11.5%, and net photosynthetic rate of ear leaf decreased by 22.85% and 18.14%, respectively, compared with the control.

结果表明：大喇叭口期到成熟期增温显著降低了夏玉米籽粒产量，ND108和YD13的籽粒产量分别较对照降低了46.6%和45.1%；叶面积指数平均值分别降低了15.4%和11.5%；穗位叶叶片光合速率平均值分别降低了22.85%和18.14%；两个玉米品种叶片的叶绿素a和叶绿素b含量显著降低，但对叶绿素a的影响更显著。

The average values of most traits of clones are greater than that of half-sib families except for the content of chlorophyll and the concentration of CO2 between cells.

无性系测试林的总平均侧枝数、叶绿素a含量、叶绿素b含量、总叶绿素含量和细胞间隙CO2浓度等五个指标，低于半同胞家系测试林的总平均值，其它指标大都大于在半同胞家系间的总平均值。

The result showed that the maximum chlorophyll index was more suitable for the estimation of chlorophylla concentration in the water body of Taihu Lake than the fluorescence line height in the inversion analysis for the estimation of chlorophylla concentration using MERIS fluorescence parameters, and the normalized fluorescence height (NLHR681/R665) had the best fit with the measured chlorophylla concentration.

结果表明：MERIS荧光参数中最大叶绿素指数较基线荧光高度更适合太湖水体叶绿素a浓度的反演；归一化荧光高度与实测叶绿素a浓度间的拟合效果最好。
